Yea, but they deal with each other. Some like to get really technical about their tanks. They like all the numbers right, across the line. If you think about it, because you have to read your CA numbers. So, when you raise this, it affects that, and so on, and so on. I use Crushed Coral in my tank and don't worry about KH.
